Is Retune needed after replacing axel back exhaust?

[igniter813]

Hi,

I just replaced my stock 2015 ecoboost axel back exhaust with aftermarket Pypes exhaust. Do i need to retune my car? Or will the car adjust after driving it a while?

Thanks

Generally on these cars an exhaust doesn't really do much other than change the sound. The main point of restriction on the exhaust system is the catalytic converter. To really make a difference you'd need to put a catless downpipe on. An axleback should be completely irrelevant to the tune.

Your STFT and LTFT will tell you if you do.

No tune is needed good sir.

The car is smart enough to correct such small differences. Anything behind the cat and you're fine.
